This patch add support for NXP LS2081ARDB board which has
LS2081A SoC.
LS2081A SoC is 40-pin derivative of LS2088A SoC So, from functional
perspective both are same. Hence,ls2088a SoC dtsi files are included
from ls2081ARDB dts

Specify a channel zero in idle state to
avoid enterring tri-stated state for PCA9547.
About E-00013:
- Description: I2C1 and I2C3 buses
are missing pull-up.
- Impact: When the PCA954x device is tri-stated, the I2C bus
will float. This makes the I2C bus and its associated
downstream devices inaccessible.
- Hardware fix: Populate resistors R189 and R190 for I2C1
and resistors R228 and R229 for I2C3.
- Software fix: Remove the tri-state option from the PCA954x
driver(PCA954x always on enable status, specify a
channel zero in dts to fix the errata E-00013).

NXP Erratum A008585 affects A57 core cluster used in LS2085rev1.
However this problem has been fixed in A72 core cluster used in LS2088.
Therefore remove the erratum from LS2088A. Keeping it only in LS2085.

Please ensure the patch doesn't introduce additional DTC warnings. I
think 'reg' should present only in nodes with a matching unit-address.
